STEAM-TRAP.

Specification of Letters Patent.

Iratented. May 1, 1906.

Application filed February 24, 1905. Serial No. 247,071.

To (til whom, it may concern:

Be it knownthat we, CHARLES E SQUIRES and BENJAMIN F. SILLIMAN, citizensof the United States of America, and residents of Cleveland, county ofCuyahoga, and State of Ohio, have invented certain new and usefulimprovements in Steam-Traps, of which th following is a specification.

Our invention relates to improvements in contrivances provided toautomatically expel condensation from steam-pipe lines or steam-pipesystems.

The object of our invention is to render such contrivance equally aswell adapted for high and low pressure service. We attain this object inan apparatus constructed and equipped as shown in the accompanyingdrawing, which represents a vertical sectional view of said apparatus.

Like letters of reference denote like parts in the drawing andspecification.

- The chief feature of this invention consists in the valve-releasingmechanism, whiclrenables a ready discharge of the condensation in thetrap regardless of the prevalent steampressure within such traps. In themain this steam-trap comprises the vessel part A with lid B, the bucketC, the valves D and E, and a suitable bonnet, cage, and cover, referenceto which is had hereinafter.

' The vessel part A has its steam-inlet at a, and opposite therefrom islocated the lid B, which in any suitable manner may be held in secureconnection with said vessel.

A drain for the sediment is shown at l).

About centrally near the bottom of the vessel is pivotally suspended thebucket C, as at c. The bucket 0 consists of a thin metallic structureand carries in hinged connection the stem. at for the valve 1). Thelatter is thereby raised and lowered, according to position andcondition of said bucket-that is, when or as long as said bucket is inbuoyant condition the valve E is held closed against the opening 0 byand through the intervention of valve l) and stem d.

from opening e to admit of a free discharge of the water within thebucket, the water being forced out by the steamressure which isprevalent Within the vesse above the waterline, and upon discharge ofsutficient water the bucket will again ecome buoyant and raise thevalves D and E to hold the discharge-openings closed as long as thewaterline in the vessel is below the edge of the bucket.

As shown, the bonnet F is secured to the top of, the vessel, and thetube f depends therefrom well nigh to the bottom of the bucket.

On top of the tube or face of the bonnet F is secured the cage H andcover I in any suitable manner, there being a space left between saidcage and cover and a chamber hvbeing formed in the bonnet in order toestablish open relation with outlet g, wherefrom the water is conveyedto the sewer or some other place, tank, or the like.

It is preferred to make the cage a separate part from the bonnet simplyfor convenience of construction and ease of accessibility. Within thecage is formed asuitable guide it for both the valves D and E, Same iscentrally suspended from. the inner wall of cage ll, leavingopenrelation from the entrance 4. to its outlet c.

When the valve D is forcing the valve E toward its seat 6 at theentrance of opening c, then pressure will immediately exert itself onthe under side of said valve and hold same tightly against its seat, andwere it not for the opening in said valve the latter would not recede,even though the stem. d would be withdrawn by the sinking of the bucket.By way of the opening though, the pressure under valve E becomesreleased, and the latter will at once ali'ord tree exit for the waterthrough the outlet c, l'rom where it reaches the discharge branch g, asabove stated.

' From the foregoing it can readily beseen that by providing arelief-valve in connection I with the main valve any desirable discharge1%. very through said tube,-a valve-cage with top outlet secured on topof said bonnet, an apertured cone-valve seating against the top outlet,guided in said cage and furnishin a seat for said rod-Valve as shown andfor t e purpose set forth.

In Witness whereof We have hereunto set out hands this 18th day ofFebruary, A. D. 20
